		   Just from the type of *dp, you can see that this code
		   expects TIFFGetField() to be handed a double ** for
		   any TIFF_DOUBLE tag, even for the constant wc==1 case.
		   This is totally inconsistent with other fields (like
		   TIFF_FLOAT, above) and is also inconsistent with the
		   TIFFSetField() function for TIFF_DOUBLEs, which expects
		   to be passed a single double by value for the wc==1 case.
		   (See the handling of TIFFFetchNormalTag() in tif_dirread.c
		   for an example.) Maybe this function was written before
		   TIFFWriteDoubleArray() was written, not that that's an
		   excuse. Anyway, the new code below is a trivial modification
		   of the TIFF_FLOAT code above. The fact that even single
		   doubles get written out in the data segment and get an
		   offset value stored is irrelevant here - that is all
		   handled by TIFFWriteDoubleArray(). */
